Natural changes pinned to warming

Since 1970, there's been about 0.5C, 0.6C of warming - that's the global average. And look at all the effects this relatively low amount of warming has had. The researchers assembled a database including more than 29,500 records that documented changes seen across a wide range of natural phenomena, such as: the earlier arrival of migratory birds in Australia, declining krill stocks around Antarctica, earlier break-up of river ice in Mongolia, genetic shift in the pitcher plant mosquito in North America, declining productivity of Lake Tanganyika, melting Patagonian ice-fields making sea levels rise. In virtually all cases, global warming was the primary driver of change, as opposed to natural variability or other human impacts such as deforestation or water pollution.
